Music research for thriller

We have been doing research on finding copyright free music to use in our thriller opening. The fact that it had to be copyright free made it more difficult to find. However we have found a some decent music which could be used in our thriller. Firstly we went on Youtube and searched for 'copyright free music'. We found a wide range of music for this, so we decided to look at various websites which include thriller music. One website which stood out with decent thriller music was www.beatsuite.com .  This is a screen shot of this website.

We are still currently researching and trying to find our perfect soundtrack for the thriller opening.
